Please make a modification or add a setting to where appointment tags shown in blue remain blue for upcoming appointments, DO NOT disappear after the scheduled appointment time and turn red for any past due appointments. See attached screenshot for example as to what I am referring to.

The fact these tags disappear on or right after the scheduled appointment time, do not remain in sight and do not change color for a past due appointment is a HUGE oversight in terms of making sure users are able to stay on top of opportunities, appointments, etc without having to switch to their calendar tab for reference.
